Display panel and method of preparing the same

A display panel having a display region and a non-display region, comprising:

• a substrate;
• a plurality of light-emitting devices located on the substrate and located in the display region;
• a bank located on the substrate and located in the non-display region, the bank comprising a top film layer away from the substrate;
• an encapsulation structure stacked on a side of the bank away from the substrate and on a side of the light-emitting device away from the substrate;
• and
• a protective layer at least partially located in the non-display region, wherein the protective layer is located on a side of the encapsulation structure facing the substrate and laps the top film layer;
• wherein the encapsulation structure comprises a first encapsulation layer and a second encapsulation layer which are stacked, the first encapsulation layer is located on a side of the second encapsulation layer facing the substrate, and the second encapsulation layer is located in the display region and the non-display region and is in direct contact with the bank.

A method of preparing a display panel, comprising:

• providing a substrate, and pre-dividing a display region and a non-display region of the display panel on the substrate;
• forming a protective layer on the substrate, wherein at least a portion of the protective layer is formed in the non-display region;
• forming a light-emitting device on the substrate, wherein the light-emitting device is formed in the display region;
• and
• sequentially forming a first encapsulation layer and a second encapsulation layer which cover the light-emitting device on a side of the light-emitting device facing away from the substrate, wherein the second encapsulation layer is located in the display region and the non-display region, the protective layer is formed between the second encapsulation layer and the substrate, and the second encapsulation layer is formed in direct contact with the protective layer in the non-display region.
